MRB Traceability
MRB traceability is the ability to link nonconforming material to its review, disposition, approvals, and resulting actions.
MRB traceability is the ability to connect nonconforming material, parts, lots, or assemblies to the Material Review Board review record, disposition decision, approvals, and follow-up actions. It shows what was reviewed, who made or approved the disposition, what decision was taken, and how that decision was carried through production or quality records.
In manufacturing quality systems, MRB traceability commonly applies to nonconformance reports, inspection results, serial or lot records, rework instructions, scrap decisions, return-to-supplier activity, and use-as-is dispositions. It helps maintain a clear record from the original defect or deviation through containment, evaluation, disposition, and closure.
MRB traceability should not be confused with general product traceability. Product traceability follows the history and movement of material through the manufacturing process. MRB traceability focuses specifically on the quality review and disposition path for nonconforming or suspect material. In integrated MES, QMS, ERP, or PLM environments, it often depends on consistent identifiers such as part numbers, serial numbers, lot numbers, NCR numbers, work orders, and revision-controlled documents.
